IMPROVEMENT IN DEVICES FOR LUBRICATING THE JOURNALS 0F CAN-AXLES.

Specification forming part of Letters Patent No. 146,160, dated January 6, 1874i application tiled September 13, 1873.

To all whom it may concern:

Beit known that I, PHILIP BAUER, of 100 Bloomsbury, Oxford Road, Manchester, in the county of Lancaster, England, have invented certain Improvements in Lubricators for Axles, Ste., of which the following is a specification:

'lhe invention consists in the combination, with the feed-wheel and its axle, of the slotted leaf-spring, whereby the requisite pressure at the two ends of the axle of the feedwheel is provided for, as will be hereinafter set forth.

Figure 1 is a sectional view of a lubricating apparatus constructed according` to myinvention, taken in a vertical plane, y y, coincident with the axis of the car-axle, to the journal of which the device is applied. Fig. 2 is a transverse section of the same taken in the line w x of Fig. 3. Fig. 3 is a horizontal section. Fig. 4 is a vertical sectionalview taken in the same plane as Fig. 2.

Similar letters of reference indicate corresponding parts.

A is the journalfbox, having in its lower `part the receiver a, for the oil or equivalent lubricating material, and in its upper part the brass or journalbearing b, which receives the journal c of the axle B. These parts are of the usual or any suitable construction and relative arrangement.

Having reference to Fig. 1, in or upon the bottom of the oil-receiver a., and nearly or quite in the same vertical plane with the axis of the journal c above, are two perpendicular cylindrical sockets or guides, (l, which receive two spiral springs, f. Above the upper ends of the guides is a horizontal plate, G, resting on the rabbets q in the journal-box. This plate is slotted transversely in the center, as shown at Al in Fig. l, and through the slot or opening thus provided plays a flat-faced disk or feed-wheel, G1. The axial pivot G2 of this feed-wheel has its two end bearings in the boxes r on the rods t held up by springs'f,

with the upper parts of its circumference pressed against the under. side of the journal C, and the lower dipping into the oil or lubricant placed in the receiver a,sucl1 lubricating` material rising, by preference, no higher in the receptacle than the axial pivot 'of the aforesaid feed-wheel.

When the axle rotates, as in the progressive motion of the car, the journal c, by its slight frictional contact with thefeedwheel (l1, communicates a corresponding movement thereto,

whereupon oil from the oil-receiver adhering to the flat (transversely considered) face or periphery of the feed-wheel as it passes through the receiver is carried upward and over and in contact with the surface of the journal. Spreading longitudinally upon the latter, it is carried upward to the journal-bean` ing, and effectually lubricates the same.

In Fig. 4, the feed-wheel is arranged to work through a central slot in a leaf-spring, G', in

the saine manner as in Figs. l and 2. It is shown as working through the slot in the plate G. But the ends of this leaf-spring are placed upon suitable fixed supports with suicient tension in the spring itself to keep the feedwheel continually pressed up against the journal. The axial pivot of the wheel is, of course,
